    I have been very pleased with the performance of this monitor which
    has now developed a fault. The screen regularly collapses to a central
    horizontal white line and on occasion can be temporarily resolved by a
    sharp blow to the outer casing. Obviously this is not recommended, but
    suggests that the fault is not major and could be as simple as a dry
    joint. I am loathe to dispose of this excellent monitor, even though
    it is of the CRT type and no longer in favour with the masses. I would
    appreciate any feedback/advice as to the cost effectiveness of a
    repair and an indication as to what the fault might. This info would
    be useful should I be able to source an engineer locally who is
    prepared to take on the repair.

    Many thanks
  2. The horizontal white line indicates the loss of vertical sweep to the
    deflection coils. The sharp blow fix suggests a bad connection or a bad
    solder joint. One who knows some basic safety rules can narrow this down by
    flexing and poking and wiggling.
